Whenever I try to submit an image it says : Error submitting image: IO Error: no protocol/2draw/boards/publicpractice/draw/lascaux/getpng.php What can I do to fix this?

Two questions:
Does this happen EVERY time you use Lascaux? Or are you trying to submit one image and getting this every time?
If two, it might be your own problem and you probably are going to have to close lascaux and start it again, because I'm not getting this error.
If one- *shrugs* if one, I don't know why you keep using Lascaux, but unfortunatly I don't know how to help you with it.
